The recent spell of
hot weather saw solar power overtake gas as the UK's primary source of energy.
In fact, thanks to the heatwave, solar power broke several generation-related
records and became, for a small amount of time, the UK's top source of
electricity. Looks like sunshine is good for more than just a tan.
This comes as welcome
news in the wake of what has been a relatively slow year for solar
installations. The number of new solar installations has all but flat lined
over the past year but this run of mostly cloudless days has proved perfect
conditions for high power generation in this sector.
Between the 21st
and 28th of June solar power generation broke the record for weekly
output. The energy source produced 533 gigawatt hours of power. Within that
week long period, solar generated over 75 GWh on five of the seven days, which
was another record in itself. Yet another record was broken when solar output
hit a high of over 8 GW for eight days straight.
While the records will
not create any lasting impact and are mostly symbolic, it shows how far solar
power and its related technology have come in the past few years. In recent
days we have seen a return to the norm as gas and nuclear have generated the
bulk of our power.
Duncan Burt, director of system operations at National Grid, said:
“During the past 12 months alone, we have seen renewable generation records
broken and we expect this trend to continue, as technology advances and we find
new ways to accommodate and manage more wind and solar power on our network.”
On Saturday afternoon, for a total of about an hour, the solar panels
peppering the country's fields and rooftops constituted the number one source
of electricity. It contributed over 27% to the energy mix. It must be noted,
however, that to date solar power only comes top at the weekends when the
demand for power is lower.
On May 14th, earlier this year, the record for peak solar
generation was set at a whopping 9.42 GW. This is promising news for a country
with ambitions to transition fully to renewables over the course of the next
couple of decades. However, the solar capacity by the end of May this year was
12.8 GW, which is only 1.6% more than it was last May.
Unfortunately, this might be the last spike in solar power we see any
time soon as solar records are predicted to slow down. Subsidy cuts have seen
growth peter out and the incentives in place for householders to put panels on
their roofs are going to expire next year. Right now, there is no indication
that a replacement scheme will be implemented.
However, it is not all doom and gloom. Some developers believe that by
going large, they will be able to build solar projects without subsidies.
Hive Energy spoke to an industry audience last week and announced that
thanks to improvements in technology, its planned solar farm in Kent is likely
to have around 14% more capacity than originally anticipated.
The Cleve Hill scheme is predicted to have a capacity of as much as
400MW, which would completely overshadow the UK's current largest solar farm,
which is located in Wales and has a capacity of 72.2MW.
Dr Alastair Buckley, a solar expert at the University of Sheffield,
said: “This marks the start of subsidy-free solar being economically viable,
and I genuinely believe we’ll see bigger changes to the electricity sector in
the next 10 years than we’ve seen in the past 10.”
